Ok so I've been reading on here a lot about remapping everyone's cars.
Bw tuning seem to be very good.
Iv recently bought a 2005 e46 330ci, it's completely standard.
I would be interested to get it mapped, but I would like to know.
Would it end up do any damage to the engine or the car not last as long with a map?
Is there anything I should do to the car beforehand?
I'm a bit old fashioned in the sense don't play with a car and it won't go wrong,
Don't get me wrong I service the car often (every year) I even put a pipercross panel filter in, not so much for performance just for more cleaner air delivery and iridium plugs and decent oil.
So would mapping make a huge difference to standard car or would I have to put performance parts on aswel?
